How do I add a custom button on a UITableViewCell
, and then delete the cell with that button without using Interface Builder and Custom Cell?
推荐答案
如果你真的想添加一个自定义按钮而不需要子类化,只需将该按钮添加到单元格的contentView:
If you really want to add a custom button WITHOUT subclassing, just add the button to the contentView of the cell:
[cell.contentView addSubview:customButton];
您可以设置按钮的所有特征:框架,目标,选择器等...然后使用上述调用将它添加到单元格。
You can set all the characteristics of the button: frame, target, selector, etc... Ad then used the above call to add it to the cell.
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
customButton.frame=//whatever
[customButton setImage:anImage forState:UIControlStateNormal];
[customButton setImage:anotherImage forState:UIControlStateHighlighted];
[customButton addTarget:self action:@selector(delete) forControlEvents: UIControlEventTouchUpInside];
//yadda, yadda, .....
customButton.tag = 99999;
因此您可以稍后找到:
UIButton *abutton = (UIButton*) [cell.contentView viewWithTag:99999];
您需要决定WHEN何时添加按钮,也许在单元格选择,也许在编辑模式。 ..只是将代码放在你选择的委托方法中。
You will need to decide WHEN to add the button, maybe on cell selection, maybe in editing mode... just put the code in the delegate method of your choice.
